My Ca 1890 32" bbl'd 10lb 10ga Lefever undoubtedly has the widest set muzzles of any shotgun I have ever owned. Per a nice set of Starrett dial calipers measuring the closest point between the bores & then their widest point & striking an average they have a Cl/CL spacing of .915". As the OD's of the muzzles measure an even .900" that means they actually have an .015" spacing between the barrels. As they are still a full 32" long & there is no other indication I purely doubt they have been cut. They are however still a good bit shy of 1" spacing & they "Don't Touch". I didn't check the breech CL's but it is a large frame gun & they are rather wide.
